红河油田天然裂缝比较发育,水平井井网部署较密易导致压裂沟通邻井,造成井间干扰,影响邻井产量。根据红河油田的地质特征,研究压裂窜通机理。结果表明:线性流的渗流速度是径向流渗流速度的7~8倍,储层渗透率、注入压差以及井距是井间沟通的主要因素。同时,通过水平井压窜原因分析提出相应的防窜对策建议,为后期水平井开发提供一定的优化原则。
紅河油田天然裂縫比較髮育,水平井井網部署較密易導緻壓裂溝通鄰井,造成井間榦擾,影響鄰井產量。根據紅河油田的地質特徵,研究壓裂竄通機理。結果錶明:線性流的滲流速度是徑嚮流滲流速度的7~8倍,儲層滲透率、註入壓差以及井距是井間溝通的主要因素。同時,通過水平井壓竄原因分析提齣相應的防竄對策建議,為後期水平井開髮提供一定的優化原則。

Du to the reason that natural features in Honghe oilfield are well developed and well pattern deployment is dense, it is easily to channelize adjacent wells when fracturing, cause interference between wells and affect the production of adjacent wells. According to the geological characteristics of Honghe oilfield, this paper studied the fracturing channeling mechanism. The results showed that Darcy velocity of the linear flow was 7 to 8 times of that of the radial flow. Reservoir permeability, injection differential pressure and well spacing were the major factors of interwell communication. Meanwhile, through the horizontal well fracturing channeling cause analysis, this paper proposed the relevant channeling prevention countermeasure which provided optimization principles for the horizontal well development in the later stage.
